High power design | Supports both balanced/single-ended connections
Uses high-quality acoustic components | DX240 exclusive card
The "AMP8 MK2" is a "Full Voltage Discreet Amplifier Card" developed based on the "AMP8" released in the past.
Unlike the previous AMP8 which amplified voltage in 2 levels of driver and output levels, the "AMP8 MK2" operates at a consistent voltage throughout all stages, and this design allows for even lower distortion and more stable high output.
It demonstrates an excellent number of "THD+N:-114dB / Output: 980mW (32Ω load)" when connected with a single end and "THD+N:-110dB / Output: 281mW (32Ω load).
In addition to the "4.4 mm balanced output terminal", we have added a 3.5 mm single-end output terminal" which was a lot of demands.
Thats why the "AMP8 MK2" is a high quality amplifier card with a discrete design, yet the only choice for both 4.4mm balanced and single-ended connections.
No more switching cards for every device you connect to.
The inside of the "AMP8 MK2" is the same as the "AMP11 MK2" amplifier card for the DX300, with a transistor of a maximum of 2000 mA.
With plenty of power, high quality capacitors, inductors and optimized circuit design, this product achieves a "energy expression with both power and sharpness" that is difficult for small portable products.In addition, the tuning of the "AMP8 MK2" uses a capacitor that was selected according to the unique tone of the DX240, is highly conscious of the "analog feeling", and we pursued the "reality" sound that gives you a rich and lively feel.
